International ClassesB01D 017/12B01D 017/038 AbstractA computerized system for monitoring, diagnosing, operating, and controlling various parameters and processes of basket centrifuges is presented. The computer control system actuates at least one of a plurality of control devices based on input from one or more monitoring sensors so as to provide real time, continuous, operational control of certain parameters. In a preferred embodiment, the apparatus comprises a basket centrifuge with at least one sensor for providing input which is analyzed to provide information regarding cake moisture at a given time. As a result of the analysis, at least one output may be generated to activate a control device that effects changes or adjustments in the operation of the centrifuge.Other References
